Hi; I am hoping I could get some help. My 2007 Z4 3.0i recently started missing when I accelerate. I was able to borrow a diagnostic code reader from a friend and read the fault code.
The only code showing is "P135B". which is identified as "Manufacturer Contrl Ignition System or Misfire." I have been unable to locate any definitive information about this code or what might have caused it to trigger. Does anyone happen to have knowledge abut this code or have access to a resource that might give a clue what causes it?.
I cleared the fault and drove the car for about 2 hours today, checking for codes every time I would stop. For the first 1 1/2 hours no problems. I did some city stop go driving as well as some back country roads at speeds up to 115mph. The car ran ultra smooth. Then suddenly I had to slow way down to avoid hitting a bicycle on a two lane country road. As I accelerated around him I got the miss again, and it happened several times over the next 5 miles. when I stopped I had the same P135B code again.
Any help or suggestions would be greatly appreciated
